2017 Map of Cook Mountain

About this map

Cook Mtn and the steep drainages of the Lolo National Forest dominate this 2017 survey at the border of Flathead and Sanders Counties. The landscape is defined by the significant hydrological network feeding the Thompson River, which winds through the southwestern corner. Notable watercourses such as Chippy Cr, Semen Cr, and Big Rock Cr carve through the high terrain, creating sharp elevation shifts visible in Hell-Roaring Canyon and Broken Nose Gulch. This map illustrates the modern infrastructure used to navigate this mountainous timberland, primarily via the Thompson River Co Rd and Plum Creek Rd. The absence of established townsites highlights the area's primary character as a protected forest and watershed resource, where relief and drainage patterns dictate the limited human footprint.
